Prostatic Urethral Implant Delivery for Precise Atraumatic Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in developing a minimally-invasive and atraumatic system for delivering implants into the prostatic urethra, which is complex due to its tortuous anatomy and patient-to-patient variability, making accurate and consistent placement difficult.
Innovation Solution
A delivery system comprising a delivery device with multiple tubular components and a proximal control device, allowing for the deployment of self-expanding implants within the prostatic urethra, featuring a distal end with an atraumatic configuration, steerable components, and a mechanism for precise control of implant deployment and positioning.

1Object-affected harmful factors
If a minimally-invasive delivery system is used to reduce tissue trauma, then tissue trauma is minimized, but accurate and consistent placement becomes difficult due to tortuous anatomy
Solution Approach 1:
The delivery system is divided into multiple tubular components (outer tubular member, inner tubular member, distal control member) that can move independently relative to each other. This segmentation allows the system to navigate tortuous anatomy while maintaining control over implant placement precision through coordinated movement of each segment.
Solution Approach 2:
The distal control member acts as an intermediary element that extends through the inner tubular member to the distal end, providing direct control over the implant deployment mechanism. This intermediary structure enables accurate placement by allowing the operator to control implant release independent of the delivery catheter position.
2Ease of operation
If the delivery system is made flexible to accommodate tortuous anatomy, then ease of delivery is improved, but control precision over implant deployment deteriorates
Solution Approach 1:
The flexible delivery system is segmented into multiple tubular members that can flex and navigate tortuous anatomy independently. Each tubular member maintains structural integrity while allowing relative movement, enabling the system to be both flexible for easy delivery and precise for controlled deployment.
Solution Approach 2:
The delivery system employs dynamic relative movement between the inner tubular member and outer tubular member. By allowing these components to move independently, the system adapts to tortuous anatomy during delivery while maintaining precise control over implant deployment through the distal control member mechanism.
3Reliability
If self-expanding implants are used to maintain urethra in partially open state, then therapeutic effect is improved, but deployment control becomes more complex
Solution Approach 1:
The distal control member serves as an intermediary mechanism that simplifies the deployment of self-expanding implants. By providing a dedicated control structure that extends to the implant, the system enables reliable deployment control without requiring complex external deployment mechanisms, maintaining therapeutic reliability while managing device complexity.
